To be honest, I could not believe that this was happening to me. I know that this is a huge cliche but it felt like a dream. I almost had to pinch myself to ensure that I was awake. And today, after months of hard work, I am proud to announce that my Spring Data book is published. All Theory And No Play I have read my share of programming books and noticed that many of them have two common problems: The book is all about theory. These books are great if you want to impress your buddies and seem smarter than you really are. However, if you want to actually learn something, it can be hard to apply the theory to practice. The sample code of the book is considered only as a byproduct. In other words, the sample projects might be messy and it can be hard to run them. I hate this. I wanted to do something different. Spring Data is a practical hands-on guide and it includes only the theory that is absolutely necessary. As an additional bonus, you receive fully functional example applications that demonstrate the topics covered in this book.

I wanted to do something different. Spring Data is a practical hands-on guide and it includes only the theory that is absolutely necessary. As an additional bonus, you receive fully functional example applications that demonstrate the topics covered in this book. The Power of Two As Chinese say, good things come in pairs. It teaches you to manage your entities and create database queries in an easy and productive way. The best part is that you can do this with less code than ever before.

The second part describes how you can use Redis key-value store in your Spring powered applications. You might also want to read this blog post by Boris Lam: However, I will also answer to the questions which you made in your original comment.

When you are adding custom methods to a single repository, the name of the class which implements the custom interface must be created by following this formula: If you use the default value of the repository implementation postfix and the name of the actual repository interface is ContactRepository the name of the class which implements the custom interface must be ContactRepositoryImpl.

You made a good point when you mentioned that my book mostly explains how and leaves the why out of the picture. I will try to explain the benefits of adding custom methods to repositories in the following.

However, there are situations when you might want to add custom methods to your repositories. These situations include:. Also, I agree that example might not work as good as I intended when you read it from a book.

Have you downloaded the example source code from the website of Packt Publishing Click the Support tab? I think that seeing the whole source code would be extremely beneficial to you. I posted a thread at http: The problem is that Spring Data JPA cannot parse the executed query from the method name of your query method. Also, you do not need to implement a method which returns all Admin objects stored to the database.

You can use one of the following methods:. About my book.

I did not even try to implement a findAll method by using query methods because the repository interfaces already offer several methods from which to choose. I was looking in your book for some information on how to do an update Query as I have trouble doing my first one but I could not find any example of it. It would be nice to have and would fit well in your book. Indeed, the user might need some guidance as I have seen posts on Stackoverflow from people running in trouble trying to do this basic thing.

Myself as well: It is nice to hear from you again, especially since you have an another interesting use case which was not covered in my book. However, since this is not useful to you right now, I will take a closer look at this.

My Spring Data Book Is Out

I was able to reproduce this issue with the example application of my blog post which talks about the integration testing of Spring Data JPA repositories. Unfortunately I cannot provide you an answer right now but I will let you know after I have found a solution to this problem. I was able to solve the problem by annotating the test method with the Transactional annotation. I wrote a more detailed answer to your Stack Overflow question.

Do I need to do it in my repository or in Service. Save my name, email, and website in this browser for the next time I comment. Previous Post: Next Post: Petri Kainulainen.

My Spring Data Book Is Out

You did a great job! Petri Link November 10, , Stephane Link May 28, , Anyway, thanks for your articles and your good book! Kind Regards,. Petri Link May 28, , Hi again Petri, I now saw how to inject my domain class repository using the Autowired annotation.

It was hidden in plain sight: Hi Stephane, You mentioned that you wanted to create a base repository implementation which is shared by all repositories. These situations include: You want to hide the implementation details of your repository layer from the service layer.

If want to take a purist architectural point of view, the upper layers of an application should not know the implementation details of the lower layers. You can hide these details by adding custom methods to your repositories because after you done this, the service classes deal only with interfaces.

This scenario is actually demonstrated in the chapter four of my book. For example, you might want to implement a search function which uses external search server like Solr but executes the query against your database if the Solr server is down or no results is found. Stephane Link June 7, ,
